Ok first off you copied the same mistake someone else made. If you set wavelength to 12 + SECS_PER_HOUR then it will be 72 minutes per high tide to low tide. Should be 12 * ... Unless you're troubleshooting maybe.

Also you only set tideSpeed once when you declare it so it isn't updating. Try setting it inside loop instead. Also you have w_sethour and label_rise_hr which are the same value. You could just consolidate them and reduce the number of variables you need.
